I still think there are 5 more VAs with admiral codenames.
Aokiji, Akainu, Kizaru, Fujitora and Ryokugyuu are all based off of the Chinese Zodiac, so 5 of the 12 animals depicted.
Funny enough, the world conscription was supposed to a sort of "competition" to see who would replace Aokiji and Akainu, and Fujitora and Ryokugyuu were the victors. We know there were losers because while they aren't Admirals, Momosagi and Chaton are 2 Vice Admirals with Admiral codenames, being Pink Rabbit and Brown Pig respectively. Idk if they actually fought each other but seeing as Akainu is Fleet Admiral I wouldn't be surprised.
So currently, we have:
- Akainu (Red Dog): Fleet Admiral
- Aokiji (Blue Pheasant): Not a Marine
- Kizaru (Yellow Monkey): Admiral
- Fujitora (Purple Tiger): Admiral
- Ryokugyuu (Green Bull): Admiral
- Chaton (Brown Pig): Vice Admiral
- Momousagi (Pink Rabbit): Vice Admiral
Which leaves Dragon, Rat, Goat/Sheep, Snake, and Horse with any associated colors. Just to note, someone could technically take Aokiji's so there could be 6 unknown VAs. It's also possible he's still a marine but just undercover.
Anyway, if you don't include Aokiji, that leaves 11 members to fit this Zodiac theory, which is coincidentally the same number as Blackbeards main crew (him plus 10 captains) and potentially Luffys crew post Wano.
Maybe we get a pretty solid battle with Luffy's crew and these 11 Marines in the final war
